airportfyi

Python API client for global airport data. Look up 4,500+ airports by IATA/ICAO code, query runway specifications, explore terminal configurations, and retrieve geographic coordinates — all from AirportFYI, an airport reference platform with comprehensive data on commercial and regional airports worldwide.

Built on authoritative aviation data sources, AirportFYI covers IATA/ICAO code assignments, airport classifications (international hub, regional, domestic), runway dimensions, elevation, timezone, and country information — used by travel-tech developers, flight tracking apps, and aviation data platforms.

Explore airports at airportfyi.com — browse by country, search by IATA code, and view airport details.

What You Can Do

IATA and ICAO Codes

Every commercial airport is assigned two identification codes. The IATA code (3 letters) is used on boarding passes and booking systems — familiar codes like LAX, JFK, NRT. The ICAO code (4 letters) is used in flight plans and air traffic control — KLAX, KJFK, RJTT. The first letter(s) of ICAO codes indicate the geographic region.

ICAO Prefix	Region	Examples
K	Contiguous United States	KJFK, KLAX, KORD
C	Canada	CYYZ, CYVR
EG	United Kingdom	EGLL (Heathrow), EGKK (Gatwick)
LF	France	LFPG (CDG), LFPO (Orly)
RJ	Japan (mainland)	RJTT (Haneda), RJAA (Narita)
RK	South Korea	RKSI (Incheon), RKSS (Gimpo)
Z	China (mainland)	ZBAA (Beijing), ZSPD (Pudong)
WS	Singapore	WSSS (Changi)

from airportfyi.api import AirportFYI

with AirportFYI() as api:
    # Look up by IATA code
    results = api.search("ICN")
    airport = results[0]
    print(f"{airport['iata']}/{airport['icao']} — {airport['name']}")
    # ICN/RKSI — Incheon International Airport

Airport Classifications

Airports are classified by traffic volume, runway capability, and role in the air transport network. Major international hubs handle 40M+ passengers annually and serve as connection points for global airline alliances.

Classification	Annual Passengers	Characteristics
Large Hub	1% + of total (40M+)	Multiple terminals, long-haul routes
Medium Hub	0.25-1% (10-40M)	Domestic + some international
Small Hub	0.05-0.25% (2-10M)	Regional service
Non-Hub Primary	10K-2M	Essential air service
Regional/GA	<10K	General aviation, private

from airportfyi.api import AirportFYI

with AirportFYI() as api:
    # Browse airports by country
    airports = api.list_airports(country="united-states")
    hubs = [a for a in airports if a.get("classification") == "Large Hub"]
    print(f"{len(hubs)} large hub airports in the US")

Runway and Elevation Data

Runway length determines what aircraft can operate at an airport. Widebody jets (B777, A380) typically require 3,000m+ runways, while regional turboprops can operate from 1,500m. Airport elevation affects takeoff performance — high-altitude airports like La Paz (4,061m) require longer runways due to thinner air.

Runway Category	Length	Capable Aircraft
Short (<1,500m)	4,921 ft	Turboprops, light jets
Medium (1,500-2,500m)	8,202 ft	Narrowbody (A320, B737)
Long (2,500-3,500m)	11,483 ft	Widebody (B777, A350)
Ultra-long (>3,500m)	11,483+ ft	A380, high-altitude ops

from airportfyi.api import AirportFYI

with AirportFYI() as api:
    # Get runway specifications
    airport = api.get_airport("denver-international")
    print(f"Elevation: {airport['elevation_ft']} ft")   # 5,431 ft
    print(f"Runways: {airport['runway_count']}")

Geographic and Timezone Data

Every airport entry includes precise latitude/longitude coordinates and IANA timezone identifier, enabling distance calculations, flight time estimation, and local time display in travel applications.

from airportfyi.api import AirportFYI

with AirportFYI() as api:
    airport = api.get_airport("tokyo-haneda")
    print(f"Lat: {airport['latitude']}")       # 35.5533
    print(f"Lon: {airport['longitude']}")      # 139.7811
    print(f"Timezone: {airport['timezone']}")   # Asia/Tokyo
    print(f"UTC Offset: {airport['utc_offset']}")
